Problems solved by technology
The disadvantage is that the sludge drying efficiency is low, especially the drying treatment of high water content sludge, which cannot be well matched with the plasma gasification melting furnace. Moreover, the application of waste heat in this patent document is only drying through heat exchange. Sludge and promote the absorption effect of activated carbon in the later stage, and the resource utilization rate is low

Embodiment Construction
[0033] The present invention is not limited to the following specific embodiments. Those skilled in the art can implement the present invention in various other specific embodiments according to the disclosed content of the present invention, or make simple changes or All changes fall within the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0034] The present invention is described in further detail below in conjunction with embodiment:
[0035] A sludge treatment system combined with drying and plasma gasification melting, including:
[0036] The sludge drying system includes a low-temperature jet drying system connected in sequence for reducing the water content of the wet sludge to 10% to 50% (weight), and a low-temperature jet drying system for reducing the water content of the wet sludge to 10% (weight). ) belo...

The invention belongs to the technical field of sludge treatment, and relates to a sludge treatment system combining drying and plasma gasification melting and a method thereof, and the system comprises a low-temperature jet drying system, a low-temperature waste heat drying system, a plasma gasification melting system and a synthesis gas post-treatment system which are connected in sequence, and the synthesis gas post-treatment system comprises a first waste heat exchanger, a dust remover, an alkaline washing tower, an induced draft fan, a gas generator set, a waste heat exchanger and an SCR catalytic tower which are sequentially connected. The sludge drying system has a better drying effect, can dry high-water-content wet sludge until the water content is lower than 10% (weight), effectively improves the dry basis heat value of the sludge, reduces the sludge treatment energy consumption, and reduces the operation cost. The heat of the rear-end plasma gasification melting system is used for the low-temperature waste heat drying system, electric energy generated by the gas generator set is used for the low-temperature jet flow drying system, on one hand, effective recycling of resources is achieved, and on the other hand, electric energy is well saved.
Description
technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a sludge treatment system and treatment method combined with drying and plasma gasification and melting. Background technique [0002] As a kind of solid waste, sludge has become the second largest source of solid waste pollution after municipal waste pollution. Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. Traditional sludge disposal methods include landfill, incineration, sea discharge, and agricultural use. However, the traditional treatment methods also have some disadvantages. They cannot utilize the sludge as a resource, and cannot meet the current technical requirements for sludge treatment. Chinese patent document (application number 201710300821.0) discloses a high-temperature plasma gasification melting treatment system and method for industrial waste, including a sludge thin-layer drying machine, a dry...
